Holiday travelers are advised to expect snowy conditions through the night along Interstate 70 and other mountainous routes, the Colorado Department of Transportation advised in a Saturday news release.

I-70 between Vail Pass and Empire was closed on and off all afternoon Saturday due to multiple accidents. Harsh weather conditions are creating an unsafe driving environment.

"Crews are working to reposition their plows to focus on westbound from Empire to the tunnel," the CDOT release said.

The National Weather Service (NWS) predicts a winter weather advisory will be in effect until 11 p.m. tonight, bringing heavy snow in spots, blowing snow, slippery road conditions and poor visibility.

"There is a potential for high gusty winds in some areas as well," CDOT advises.

Snow accumulation is predicted to be between 4 and 8 inches in some of the heavier areas. "Motorists should also be advised of potential avalanche mitigation on Loveland Pass and Berthoud Pass Sunday morning," the release also advised. "The avalanche control work will cause travel delays while operations are taking place and plows then clear the roads."

“We strongly urge motorists to take it slow when traveling to your destination," said Kyle Lester, CDOT Director of Highway Maintenance.

A late Saturday evening closure of US Highway 40 along Rabbit Ears Pass was also issued by CDOT.
